I have a Mazda 3 Coupe and was wondering if anyone has removed the Mazda symbol and the Mazda 3 logo. Is it glued on? Would it require body work if it was removed?

 

There are holes underneth. This means that you would need to have it done proffesonally.

 

On the same subject, my '02 rear trunk lid, the "MAZDA" and the slanted "Protege" emblems are looking really cruddy around them and between the letters, from waxing, etc. Is there a way to remove them and re-install them without breaking the nubs off that appear to be holding them in/on?

 

Not sure.
I think you can just pry them off, like everything on these cars. Im pretty sure theyll just clip off, just be carefull.
